Abstract: 378,842. Switch cases. GENERAL ELECTRIC CO., Ltd. and COLLINGS, J. H., Magnet House, Kingsway, London. May 18, 1931, No. 14175/32. Divided on 378,118. [Class 38 (v).] In order to allow a wallbox carrying a switch to be set for receiving either horizontal or vertical conduits, and in order to permit of rotational adjustment of the switch to correct for inaccuracies in the setting of the wall-box, the switch is mounted on a metal plate 21 pivoted at the back of the wall-box by a screw 23. Nuts 20 which clamp the switch-mounting screws to the plate 21 project into either of two pairs of short arcuate blind holes 22 (one pair only shown), the arrangement allowing the switch to be adjusted, and to be selectively placed in either of two positions at right-angles.

Title: Process for the removal of acetylenic hydrocarbons from mixtures of gases or vapours
IPC: C07C7/148
Filed: 1943-09-01
Abstract: Acetylenic hydrocarbons are removed from gas or vapour mixtures by contacting at a temperature not above 0 DEG  C. with a solid complex of caustic potash and an acetal, ketal or glycol dialkyl ether.  The complexes are preferably melted in presence of the excess reagents and cooled while agitating to produce a microcrystalline form of high activity.  The acetal, ketal or glycol ether is preferably one boiling above 100 DEG  C. when the caustic potash may be added in any available form and the mixture heated to about 110-150 DEG  C. to melt the complex formed.  With lower boiling reactants, powdered caustic potash or heating under pressure is necessary.  Acetals specified are those formed from methyl ethyl ketone and ethylene glycol, 2-ethyl hexanal and methyl alcohol, butyraldehyde and propyl alcohol, and acetaldehyde or butyraldehyde and butyl alcohol.  The complexes are used for removing acetylenes from crude butadiene or industrial waste gases.  The acetylide produced can be hydrolysed to recover the acetylene or reacted with a ketone or aldehyde as described in Specifications 573,527 and 580,921.  Butadiene containing 10 per cent of acetylenes is passed at between 0 DEG  and -10 DEG  C. through a suspension of the microcrystalline complex made from caustic potash and acetaldehyde-dibutylacetal, preferably under conditions such that the butadiene does not remain liquefied.  The absorption product is treated with acetone at about -10 DEG  C., decomposed with water and the acetal layer distilled to recover 2-methyl-5-hexene-3-ine-2-ol.

Abstract: 907,681. Television. TELEFUNKEN PATENTVERWERTUNGS - G.m.b.H. April 21, 1961 [April 23, 1960], No. 14505/61. Class 40 (3). Relates to a television camera remote control arrangement for selectively bringing into use any one of a plurality of camera objective lenses. At the control point 18 there is provided for each objective lens a switch 19, 21, associated with an electromagnetically releasable selfholding mechanism 20, 23, 24, 25, which completes an individual circuit to a relay R at the camera. A first relay contact r 1 , completes a circuit for motor 22 which rotates the lens turret to bring the selected lens into use, whilst a second contact r 2  opens the release circuit for the self-holding mechanism. When the lens reaches its operative position, a contact 26 is operated by the turret thereby releasing relay R to stop the motor and remake the release circuit 20 as to restore the switch at the control point. The invention is described as applied to an arrangement, Fig. 1 (not shown), for controlling nine television cameras each with a turret having three objective lenses. The cameras are associated in groups of three with switch-over devices for selecting a desired camera output for application to a unit for forming a standard television signal for onward transmission. Associated with the unit there is provided a lens selection unit arranged as described with reference to Fig. 1 and having a total of 27 switches, one for each objective lens.
